Installation

1. Clone the Repository

   git clone https://github.com/ltc6539/mcp-ppt.git
   cd mcp-ppt
   

2. Create a Virtual Environment (Optional but Recommended)

   python3 -m venv .venv
   source .venv/bin/activate  # On Windows use: .venv\Scripts\activate
   

3. Then add MCP to your project dependencies

   uv add "mcp[cli]"
   uv run mcp
   

You can install this server in Claude Desktop and interact with it right away by running:

mcp install server-local.py

Alternatively, you can test it with the MCP Inspector:

mcp dev server-local.py

If the claude desktop has error, You may need to put the full path to the uv executable in the command field. You can get this by running which uv on MacOS/Linux or where uv on Windows. During startup, the server logs Python and python-pptx version information to stderr. Any errors during execution are also printed to stderr for easy debugging.
